Depends on the use case. And even at 1080p there are quite a few games that use 8gb or close to it. Ghostrunner and LOTF (2023) come to mind. Although tbf, I played the first one on my RX580 8G (I think) almost maxed out and it did fine.
But if you’re buying a card now, especially at new modern card prices, you want to have at least a bit of future proofing.
